HEEL-FINISHING MACHINE.

Specification of Letters Patent. P t t d Feb, 22, 1910.

Application filed July 16, 1908. Serial N 0. 443,828.

To all whom it may concern:

Be it known that I, CHARLns 'PEAsE, a citizen of the United States,residing at. Beverly, in the county of Essex and Commonwea-lth ofMassachusetts, have invented certain Improvements in Heel-FinlshlngMachines, of which the following descr1ption, in connection with'theaccompanylng drawings, is a specification, like reference characters onthe drawings indicating like parts in the several figures.

This invention relates to machines for finishing shoes and particularlyto heel burnishing machines and a feature of this invention consists ina. novel construction and arrangement of means for applying wax andworklng it into heels. This means as herein shown comprises a burnishingtool which will preferably be a fluted wheel having an unyieldingworking surface adapted to carry wax'in the low portions or grooves andto rub the wax into the heel by the high portions or ribs. Cooperatingwith this wheel is a wax holder containing a waxdelivering disk forlifting the wax and depositing it upon the high portions of theburnishing wheel from which it is rubbed into the low portions of thewheel by the engagement thereof with the work. The wax holder has aslidin fit in a guideblock in which it can be ad usted by a screw thatis held against endwise movement in the block and takes into the holder.This permits very accurate adjustment of the holder with relation to theburnishing wheel. For the purpose of allowing rougher adjustments,

as when a burnishing wheel of different diameter replaces one previouslyused, the guide block is arranged for lengthwise movement in a clamphaving a convenient operating device and the clamp is itself pivotallymounted on a bracket which is bound to a circular support or rod alonwhich the bracket and partscarried by it can be adjusted' to positionthe wax-feeding disk with relation to the width of the burnishing wheeland about which the bracket can be adjusted to bring the contact pointof the disk and wheel at the desired elevation. The pivotal connectionof the clamp with the bracket, which together with the'contact point ofthe wheel and disk isbelow the axis of the wheel, permits the holder torock downwardly to prevent breakage in case any obbeveled gear thatmeshes with a similar gear on a short depending shaft that is supportedby the holder and carries a belt pulley. This receives a beltthatextends to a pulley on a similarly mounted shaft which in turn isdfi'iiirpn through beveled gears from a driving s a t.

A desirable feature of this construction is found in the use ofintermeshing gears that are made of different materials whereby thenoise incident to the driving engagement of the gears is materiallylessened as is also the wear. One of the gears may be made of iron asusual, while the cooperating gear will preferably be made of anon-metallic composition, such, for example, as that used in themanufacture of the higher grades of fiber board.

In manyof the smaller shoe manufacturing establishments both shoeshaving spring heels, which have inclined breasts merging into the treadof the heel and the shank, and shoes having square heels, which havebreasts substantially perpendicular to the tread face, are made.- Theheel finishing devices which are adapted for treating square heel shoesare not adapted for treating spring heel shoes and it has heretoforebeen necessary to maintain two heel finishing machines or to change theheel finishing device frequently.

In accordance with a valuable feature of the :present invention themachine is equipped iwlth devices for finishing both spring heels andsquare heels.

The devices above described are adapted particularly 'for finishingspring heels, while mounted upon the driving shaft above mentioned thereis a heel-finishing wheel which is adapted for finishing square heelsand cooperating with thiswheel is suitable wax-supplying mechanism. Thisarrangement enables an operator to finish spring heels and square heelsin any order in which they'may come to him without loss of timeintraveling from one machine 'to another or in changing the finishingdevices. It is the custom for the operator to present the shoe heel to apolishing brush or to two or more polishing brushes havin differentcharacteristics after the heel has een treated on the finishing wheeland in accordance with this invention a single set of polishing brushesis arranged to' be used with the two sets of finishing devices.

A further advantage which is incident to the present invention is thatwax of different colors may be used with the two sets of finishingdevices so that if both black and colthe machine. 2 0

These and other features of the invention, including certaln details ofconstruction and combinations of parts, will appear in connection withthe description of the illustrated machine and will be pointed out inthe claims at the end of the specification.

Figure 1 is a plan view of the machine and Fig. 2 is an-end elevation,while Fig. 3

is a perspective view of the two sets of waxfeeding devices. 3

The head of the machine, which is supsorted ona column 2, has bearingsfor a riving shaft 4 and an auxiliary shaft '5.

t The driving, shaft, ,Which in turn may be operated from a mainvertical shaft through a worm gear, as indicated in Fig. 1, carries aheel-finishing tool 6 which may be of any suitable construction and towhich wax is fed by a disk 8 v from a wax holder 10. The Wax holder iscarried by a bracket which is angularly adjustable about a'rod orsupport 12, whereby the disk may be moved from and towardthe wheel. Thedisk is driven by a flexible shaft 14 connected through beveled gearsand a short vertical shaft 15 with a worm on the driving; shaft 4. Theauxiliary shaft 5 above mentioned is directly mounted within a sleeve 20and on its front or lefthand'end is provided with a burnishing wheel 22having an unyielding fluted peripheral working surface provided withalter nate groovesand ribs.- Awax-feeding disk 24 is mounted infabearing in a wax-holder 25 which isformed to hold a quantity of meltedwax and preferably has also a lateral extension as shown-in Fig.' 1 tohold a stick of unmelted wax. The holder has a rearwardly projectingshank or stem which is received in a gulde block 26. The guide block hasbearings in which the screw 28' is held against endwise movement. Thescrew takes into a threaded opening in the shank of the holder andforms,means by which the holder with the disk may be moved from and toward thefinishin wheel. The guide block itself is arranged or lengthwisemovement in a clamp 30, the sides of which may be forced together by ascrew provided with a handle indicated at 32. The clamp has pivotalconnection. at 34 with a bracket 35 which comprises two members alsopivoted together at 34 and formed to embrace the rod 12 beforementioned. The screw 36 has pivotal connection with one of the membersof the bracket and carries a nut 37 adapted't'o engage the other memberof the bracket. This arrangement permits the screw to be swung out ofengagement with the second member of the bracket and then the membersseparate for removing, them from or applying them to the shaft 12without necessarily moving them lengthwise on the rod. This permits thebracket 35 and the parts carried by it to be taken from the rodorsupport without removing the bracket which carries the wax holder 10.The wax holder 25- has a bearin for a vertical shaft 40 which isconnecte by bevel gears 42, 44 with the shaft of the disk 24. The shaft40 has on its lower end a pulley to receive a belt 45 which passesaround a pulley 46 on the lower end of the shaft 15. By thisarrangementboth the wax-feeding disks 8 and24 are driven from the same'shaft 15.Preferably one of the gears 16, 17 and also'one of the gears 42,

44 is formed of a' non-metallicsubstance,

such as fibroid for example, while the cooperating gear of each pair isformed of metal as it has been. found that .by the use of such. anon-metallicge'ar with a metallic gear the noisecaus'ed bytheiroperation as well as the wear is materially reduced. The flexible shaft14 is shown as formed-in two parts which are frictionally connected to,prevent breakage of the parts in case, the.

machine is started at a time when the feeding disk cannot turnas, forexample, when wax in the holder has solidified about the disk. Gasburners are provided to direct flames against the holders f 10 and 25for maintaining the wax therein in melted con dition when the machine isrunning.

The shaft 5 is driven from the shaft 4 by a large pulley on thelattershaft and a smaller one on the former connected by a belt 55whereby the shaft 5 and the burnishing wheel 22 carried by it are drivenat a higher speed than the shaft 4 and its finishing wheel. It isdesirable in finishing certain classes of work to drive the burnishingwheel at a higher speed than that which is suitable for other classes ofwork. In the present instance the relatively smaller diameter of th'wheel 22 as compared with the finishing wheel 6 reduces the apparentdifference in the surface speed of the two wheels. The sleeve shaft 20within which the shaft 5 turns is driven from the shaft '4 by a belt 56at a slower speed than the shaft 5. The sleeve shaft is utilized forcarrying the brushes 50 and 52, which may advan l at ' the machine 1fsquare heel shoes are to be finished the heels are resented to the wheel6 by which wax supp ied by the disk from the holder 10 will be appliedto the heel-and worked into the surface of the heel. When a sufficientquantity of wax has been-applied and has been properly worked into thesur face the shoe will be presented first to the brush and then to thebrush 52. If the next shoe or the next case of shoes is provided withspring heels or heels of a different type the shoes will be presented tothe tool 22 b which the Waxtransferred from the holdiar 25 by the disk24 will be applied and worked into the stock. The shoe willthen bepresented to the same brushes 50 and 52 by which the heels treated onthe tool 6 were polished. The mounting of the wax holder 25 so that itcan turn about the center 34 permits that holder to move downwardly outof the way in case any obstruction is drawn into the space between thewheel 22 and the disk 24. The clam 32 permits. adjustments ofconsiderable ength" to be qulckly made while the screw 28 provides meansfor accurately adjusting the disk with relation to-the finishing wheelto cause the disk to deliver the required amount of wax. If for anyreason the wheel is to be used without wax a turn of the screw 28 willretract the'disk far enough to prevent it from delivering the wax. Theretraction of the wax holderby the screw '28 also slackens the belt 45so that the disk may stand at rest in its retracted position.
